If all goes according to plan, about 70 proud teenagers will get diplomas when Success Academy Charter School–Manhattan High School graduates its first class in spring 2018. The moment will likely bring some sadness, though. After all, most of these students will have been together since they entered kindergarten in fall 2007.

Over the years, some students will no doubt have left the group. But, if Success sticks to its announced policies, no new students would have joined the class since 2010, when the graduates were 9 or 10 years old.
